7x + 2y=24 8x + 2y=30

Mathematics
1 answer:
Bumek [7]3 years ago
3 0

Answer:

x=6 y=-9

Step-by-step explanation:

  • Layer the equations on each other as you would in a subtraction problem:

               8x + 2y=30

               7x + 2y=24  

  • Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
  • Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves:

               42+2y=24 then

               2y=-18 then

               y=-9

  • Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.

Eleven members of the Middle School Math Club each paid the same amount for a guest speaker to talk about problem solving at the
romanna [79]
So, it's a 3 digit number that is divisible by 11, and starts with a 1, and ends with a 1.

each of them paid the same amount, let's say y and we know that if we multiply this y by 11, we'll have a number with a "2" at the end: so the last digit of y must be 2, since only 2*1=2

also, the first digit of y must be 1, since the first digit of the 3-digit number is 1.

so lets try what happens if they all pay 12 dollars? the sum is 132, so A must be 3!!!

Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?​
Ronch [10]

Answer:

i = ($650)(0.08)(1) = $52

Step-by-step explanation:

The formula for simple interest is i = prt.  Here p = $650, r = 0.08 and t = 1 (year).  Then the simple interest Deanna paid for this one year loan was

i = ($650)(0.08)(1) = $52

Help me please help please me and
Ad libitum [116K]

Answer:

x=148

Linear pairs add up to 180. Take your value of 32 and subtract it from 180 to find out the value of the remaining angle within the linear pair.

180-32=148

Hence, x=148

Hope this helps!
